In particular, spreadsheet software automatically recalculates the results when a number is changed. This capability lets business people try different combinations of numbers and obtain the results quickly. This ability to ask "What if . . . ?" helps business people make better, faster decisions.

View our project gallery — play some of the games or try out some of the apps that students have created. You can “remix” the project to make it your own, or build something new in App Lab, Game Lab, or Web Lab. In this series of eight short videos, you’ll learn how the internet was invented, what HTML is, and how search engines like Google work.

Tandem Computers Releases The Tandem

Officially known as the Track Write, the automatically expanding full-sized keyboard used by the ThinkPad 701 is designed by inventor John Karidis. The keyboard was comprised of three roughly triangular interlocking pieces, which formed a full-sized keyboard when the laptop was opened -- resulting in a keyboard significantly wider than the case. This keyboard design was dubbed “the Butterfly.” The need for such a design was lessened as laptop screens grew wider. Xerox PARC physicist Gary Starkweather realizes in 1967 that exposing a copy machine’s light-sensitive drum to a paper original isn’t the only way to create an image. So in 1971, Starkweather transferred to Xerox Palo Alto Research Center , away from corporate oversight. Within a year, he had built the world’s first laser printer, launching a new era in computer printing, generating billions of dollars in revenue for Xerox.

The DN100 is based on the Motorola microprocessor, high-resolution display and built-in networking - the three basic features of all workstations. Apollo and its main competitor, Sun Microsystems, optimized their machines to run the computer-intensive graphics programs common in engineering and scientific applications. Apollo was a leading innovator in the workstation field for more than a decade, and was acquired by Hewlett-Packard in 1989.

These devices supplement the computer's memory, which, as we will see, can hold data and programs only temporarily. Physical structure that houses a computer's processor, memory, storage, communication ports and peripheral devices. Each of these components have a different purpose, which may be either accepting inputs, storing data or sending outputs. The semantic Web is an effort to enable lay people to find, share, and combine information available on the web more easily. The name was coined by Berners-Lee to describe “a web of data that can be processed directly and indirectly by machines.” It is a framework for data sharing among applications based on the Resource Description Framework .

Among the lecturers were early computer designers like John von Neumann, Howard Aiken, J. Presper Eckert and John Mauchly, as well as mathematicians including Derrick Lehmer, George Stibitz, and Douglas Hartree. Students included future computing pioneers such as Maurice Wilkes, Claude Shannon, David Rees, and Jay Forrester. This free, public set of lectures inspired the EDSAC, BINAC, and, later, IAS machine clones like the AVIDAC. Conceived by Harvard physics professor Howard Aiken, and designed and built by IBM, the Harvard Mark 1 is a room-sized, relay-based calculator.

Hour Of Code

We choose to focus on ARM because it is a commercial leader and because the architecture is clean, with few idiosyncrasies. We start by introducing assembly language instructions, operand locations, and common programming constructs, such as branches, loops, array manipulations, and function calls. We then describe how the assembly language translates into machine language and show how a program is loaded into memory and executed. Studyingcomputer graphicsinvolves using computers to create still or moving two or three dimensional images using specialized graphics hardware and software.

A computer is made up of multiple parts and components that facilitate user functionality. The diffusion of smartphones, game consoles, wearables, and smart appliances made computers much more readily available in our daily life. As of November 2021 the most powerful computer in the world is the Japanese supercomputer Fugaku, developed by RIKEN and Fujitsu. We’ve created a new place where questions are at the center of learning. Britannica celebrates the centennial of the Nineteenth Amendment, highlighting suffragists and history-making politicians.

You’ll study how to manipulate visual and geometric information using computational techniques, focusing on mathematical and computational foundations of image generation and processing rather than purely aesthetic issues. You’ll need knowledge of physics, light and materials, as well as knowledge of the mathematics of homogenous matrices, and of data storage, representation and manipulations. Computer graphics makes the interaction and understanding of computers and interpretation of data easier for both computing professionals and consumers. With companies exploring increased use of trends such as ‘gamification’, the demand for computer scientists with advanced knowledge of computer graphics has never been greater.

Learn binary and other number bases, tools to understand sequences of numbers, how to represent space numerical using coordinates, and study variations of quantities via functions and their graphs. Solve computing and everyday life problems using these tools, from sending secret messages to designing computer graphics. Introduction to Computer ProgrammingThis course provides the foundational skillset required to write computer programs. You’ll learn how to write interactive, graphical programs from an introductory level in a real programming language. Amultimedia programmeris responsible for designing and creating multimedia computer products, making sure they are functional and maintaining fidelity to a designer’s specification.
